It is heartening to see
It is heartening to see our friends' love for dance. We are all made up of tissues - made up of cells having atom within it and these atoms in each cell keep on moving rather dancing. This is called Brownian movement or motion, zigzag, irregular motion exhibited by minute particles (atoms) in matter. This is the reason why we all are in love with dance inherently.
Best mode to emote out
True!
There are unseen stress, humilations, pain, etc., keep on piling without our knowledge - dance helps us to emote powerfully - you can cry, suffer, feel terrible, all these emotions releases those piled up negative emotions and make you light and cheerful.
Frankly speaking.....
Frankly speaking....I dance not....but my mind.
Its the state of mind that makes my body move....To throw light on darkness within....or for enlightment/enhancement...I dance.....dance to the tunes of my mind.
I dance when I'm happy, when I'm sad, when I'm excited, when I'm lifeless......Inshort....when I'm myself. Dance is my life blood. Even when my body isnt dancing, my mind will....its just like my heart beat. It never stops...when it stops....my soul never exists.
Dance has embedded a lot of values in me...like communication...through ur body, ur eyes, ur face. So, i cherish dancing, will continue to cherish & will try to enhance it in the way my mind takes it. :D
